fix(tests): resolve ADM-001 regressions in Api.Tests fixture

- Update hardcoded permiso count from 21 → 22 in AuthControllerTests and
  PermisosEndpointTests after V011 added 'administracion:secciones:gestionar'
- The TestSupport SqlTestFixture already had Medio_History/Seccion_History in
  TablesToIgnore; tests were failing due to stale binaries (needed rebuild)
